About
R. Brian Haynes is a towering figure in evidence-based medicine, whose work has fundamentally shaped how clinicians and researchers access and apply medical knowledge. His key research areas include the development of evidence-based practice tools, clinical decision support systems, and the evaluation of medical information resources. Haynes is best known for pioneering the "4S" and "5S" hierarchies of pre-appraised evidence, which guide users from original studies to synthesized summaries and systems, revolutionizing how busy clinicians find reliable answers. He also led the creation of ACP Journal Club and the McMaster Premium Literature Service (PLUS), critical resources that distill high-quality research for practice. With over 100,000 citations to his work, his impact is immense—his 1994 JAMA paper on the "evidence-based medicine" movement alone has been cited more than 10,000 times. A former editor of the journal *Evidence-Based Medicine*, Haynes has received numerous awards, including the Canadian Medical Association's Medal of Honour, for his relentless pursuit of bridging research evidence with patient care. His legacy endures in the daily workflows of clinicians worldwide.
